It cuts right-hand direction and handles minimum bore diameters starting at 0.36 inches, with a maximum bore depth of 1.25 inches. The 3\/8-inch shank diameter and 2.5-inch overall length make it well-suited for compact setups on CNC lathes and boring machines. A bright finish coating is applied to the flute and shank. Corner radius range runs from 0.005 to 0.008 inches, giving machinists precise control over internal corner geometry on finished bores.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use in precision machining environments where internal bore finish and corner radius accuracy are critical. Typical applications include producing close-tolerance bores in ferrous and non-ferrous workpieces on CNC turning centers or manual lathes. The submicron carbide grade supports demanding cuts where tool wear resistance and edge retention are priorities. It is selected by machinists, toolroom operators, and job shop technicians working on components that require consistent internal geometry across production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for superior wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for controlled internal corner profiling\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.36 inches suitable for small-bore internal work\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.25 inches accommodates typical short-to-medium bore applications\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shank diameter for compatibility with standard boring bar holders\u003c\/li\u003e\n\u003cli\u003eBright finish coating on carbide substrate\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or toolroom addition for standard 3\/8-inch boring bar holder setups used in CNC turning and manual lathe applications requiring right-hand internal corner radius cutting.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool turret or holder is locked before inserting or removing the boring bar. Secure the shank firmly in the boring bar holder to the holder manufacturer's specified clamping torque using appropriate tooling screws. Verify tool centerline height and overhang before beginning a cut to avoid chatter or premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Range\u003c\/strong\u003e: 0.005 to 0.008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1875 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B3601250R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737175261490,"sku":"B3601250R","price":80.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80da4216b237bbfccca22ed29b59e445.jpg?v=1788785234","url":"https:\/\/voomisupply.com\/products\/accupro-b3601250r-corner-radius-boring-bar-submicron-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
